The emplacement of an integrated surface power system and its related infrastructure on the lunar surface is an extremely

important effort for the successful establishment of a permanent manned presence on the moon. These power systems

and infrastructure must survive hostile launch environments from the earth’s surface as well as being reasonably sited,

operated, and maintained in another relatively hostile setting. This report investigates numerous emplacement options

and conceptual ideas for power system hardware. It provides (among other things): very preliminary values for equipment mass and size; task breakdown descriptions for hardware emplacement; the required heat, forces, torques, and

alignment tolerances for equipment assembly (where capable of reasonable estimation). Since the concepts presented in

this report are very preliminary, this document spends some time detailing the important issues which must be resolved

before undertaking the design of complete integrated power plants and their related infrastructure systems. For example,

the shock, vibration, acoustics, and quasi-static accelerations expected to be exerted on the power plants and infrastructure hardware during their flight from launch to the lunar surface must be developed.
